be quiet! Dark Base Pro 900 Testing:

Testing involved recording temperatures in degrees Celsius for the CPU and GPU during idle and load phases. The load was simulated by running Prime95’s small FFTs and 3DMark Vantage for one hour. The maximum temperatures were recorded using HW Monitor 1.21.0. Please note that each case is tested from its factory setup, including the location of fans, unless otherwise noted.

The thermal performance was about where I expected it to be for a case this size. With the 140mm SilentWings® 3 fans moving the air through the case, the heat from a mild overclock was not a concern. The best performing case I had tested up to this point was the Thermaltake Core X9, which is a large case with a lot of internal volume. And thanks to the large volume of the Dark Base Pro 900, the thermal performance was similar to the Core X9. The cooler temps are no surprise, but keep in mind that the Core X9 and the Dark Base Pro 900 are very different cases. The extra sound deadening material in the Dark Base Pro 900 goes a long way towards keeping the fan noise under control.

When I examined the case with the FLIR camera, the heat was concentrated at the top rear of the case, where the rear 140mm SilentWings® 3 exhaust fan pushes the warm air out of the case. Of course, the fans of the Noctua D14 move air toward the rear exhaust, so that is where I saw the heat concentrated. If I had used a top mounted radiator or installed exhaust fans at the top, I would expect to see heat coming out of the top vent, but the heat was really concentrated at the top rear of the case. The rest of the case was cool and quiet.

Looking at the right-hand picture, I usually see the heat from the power supply, too, but with the power supply inset and behind the mesh panels, it was not as obvious.

Then there is the heat from the GPU, and since it is a reference (blower) style, the hot air is pushed out of the case. While I like the way a blower style GPU rejects hot air from the case, they tend to be louder. However, in the Dark Base Pro 900, the GPU seemed a bit quieter when it was under a load. As far as GPU temperatures are concerned, with a reference card I really see about the same thermal performance regardless of the case.
